What about steps per mm on the extruder? Calibrated?

Im not sure if i can do that on the stock firmware of the davinci jr 1.0. But when it did print and i printed a calibration cube, it was spot on.


The extruder calibration is different. I forgot you where on a stock machine so you can't really calibrate the extruder either. Maybe the filament is binding somewhere then.

thats my guess and it seems that its somewhere in the extruder motor area. i think the gears may be to worn out?

oh, and my threaded z-rod is out-of-round as well. you can see it wobble as you make the print head move up

Did you run an auto PID after the install? It may be having problems maintaining heat and the auto PID might help.

Im still using stock FW. im not going to convert to ramps. I did watch the temps though and they stayed right at 205 the entire print

Thanks

I hjust tested other filiments and same issue, in same place.

I just canceled the print, and i know its not a clog because hte nozzle is still pushing out filiment:)

It works about 50% of the time, then the filiament stops flowing. Orginially i thought it was a clog, but as soon as i cancel the print, and restart, the flow is fine. I personally think its the bowden setup. The gears all of a sudden just start grinding and clicking and cant seem to push the filiment.. almost like its a clog, but like i said, once i restart the print, no clog.

Things i think it is:
bad filiment(sunlu)
bad gears and bad bowden motor. it sounds bad even when the gears are not slipping
possible clog

What ideas do you guys have?

thanks
